cylonlover writes: The Defense Advanced Research Projects Agency (DARPA) is developing a foam that can be injected into the body cavities of battlefield wounded to protect them from internal abdominal bleeding. The agency hopes that when perfected, the foam will help the wounded to survive the critical minutes needed to transport them to proper surgical facilities for treatment. Developed by Arsenal Medical, Inc. as part of DARPA’s Wound Stasis program, the product is a polyurethane polymer foam designed to control internal hemorrhaging for at least an hour and is designed to be easy for doctors and surgeons to remove.
